The object of vthis invention is the provi sion of means whereby a lubricant' is posi-v tively supplied to bearings and moving partsof machinery at a pressure which isconstantly maintained at apredetermined ratio in excess of the pressure existing within vthe mechanism, regardless of any fluctuations in the internal pressure, and to eliect the same without the expenditure of any appreciable amount of energf or the provision of a coiplex organize structure.

he invention provides a unit which may be applied to compressors, rotary reciprocating or turbine pumps, water motors and analogous machinery having bearings which are subjected to internal pressure and'which are required to be lubricated to maintain their eiiiciency and to minimize .the wear of vital parts.

The invention contemplates .a cylinder divided to provide similar chambers, a

valved induction and a valved eduetion pipev connected with the inner end of each of the chambers, pistons operable in the chambers and connected for simultaneous movement, a

pressure supplying pipe connected with .the

outer end of the said l`chambers and having a four way valvein its length whereby to -Vent one of the chambers while the other chamber isuiider pressure, and a lubricant distributing pipe connected with the said eduction Y pipes and with vthe parts t0 be lubricated and having a valved-return to admit of quick adjustment of the lubricator when setting the same at givenperiods.

The invention furthermore provides amechanism of the character aforesaid which is eilicient, positive in action, simple in design and flexible in application so that it can vhe easilyconnected in a practical manner, to those various types lof machines requiring to be lubricated under conditionswhere the lubricant must be orced'to the bearings or other parts, Vunder a pressure suliicient lto overcome theresistance offered by the internal pressureof the machine. l

While the drawingsl illustrate a. *preferred embodiment of the invention, it isto be understood that iii adapting" the 'means'jto meet specific needs and r uirements, the

design may be variedand suc other changes in the minor details of construction may be v resorted to within the scope ofthe invention as claimed, without departing from the spirit thereof.

For a full understanding 'of the invention and the merits thereof, referenceisto be had to thefollowing description and they .super-pressure lubricator embodying the' iningparts.

Correspondingandlik'e Parts are referred to in the'following description and designated in the several `views ofthe drawings. by like reference characters.

The body of the lubricator -comp-rises a cylinder 1 to' the ends of which are fitted heads 2, preferably by 'means o f a screw thread connection. Aj artition -3 located centrally within f the cylinder l divides the -same into chambers, in which are located pistons 4.A Tubes 5 are fitted 'snugly within opposite end portions'of the cylinderland -receive the partition 3 between their innerv ends.

It is observed-that the outer face 'of thel vpistons is unobstructed *and v resents af maximum area toA receive the fu pressure v of the working'force. The inner'face of" thefpistons isv restricted b reason of the pressure which is in lexcess of that exerted upon the outer face'of the pistons, and which connection 6, hence the deve oped pressure is intensified .and is utilized to supply the lubricant to the parts to belubricated by a,

These" ervoir or tankffor holdingl a e valve 11 pipes'13 and114 by reason of their function inl supplying the lubricant to the cylinder may header or manifoldl isconnected to vthe valves 8 and.10 lby means voif pipes 16 and 17, which by reason oftheir operation mayl i be referred`to as eduction pi' es, since they convey the lubricant *from t e cylinder 1 to the parts to be lubricated. y This header or manifold 15 provides a ljunction or com-l 4mompoint of entryintp" the pressure service alternately operate, this header servingtheder l whereb line or delivery 'pipes 16 and 17 asthey vfurther purpose of al Icentral, distributing point from which the lubricant may be conveyed, at uniormepressure, vin opposite directio'ns, or in "one of either directions asl conditions may require.. Distributing pipes 18 are coupled to they header` or manifoldand convey the-'lubricant to the bearings or through sight feedersv 1 9.v It is-observed thatthe manifold or' header'. 15" may be locatedfat any determinate point inthe lengthof the distributing pipe v18.-""FA -return p1 e 20 connects the' distributing pipe"'1S-with t e j reservoir or tank 12 vand quick return ofthe lubricant from an end portion f. ofv the l cylinder to ,thev reservoir, thereby roviding a'means for controlling eit fritsl travel, thus makin lcertain thata full 'ment of a period of. operation.

The chambers 23. are comprised between the artition 3 and the receive the lubricant to be supplied tothe arts t0 be lubricated in the operation of the device. The

several ports open into the lubricant chambers 23. Pressure-,supplying pipes 24 con nect with the respective heads 2.l The. numeral -25 designates an exhaust pipe and '26 a supply pipederiving pressure, -in this-v instance, from the machine tobe lubricated and which mayconsist of an air compressor, 'a turbine pum a water-motor or the like.

A four-way va ve 27 is locatedat the'juncrture of the several pipes 24, 25, and 26, and

its plug 28 may be turned to direct the pressure tol either one'of the chambers 22 and to relieve the pressure from the opposite chamber22 when the device is inaction.

The numeral 28 designates generally the machine to be lubricated Aand the pi e 18 for distributing the lubricant exten s to the bearings and parts to be lubricated and ma be provided at determinate points with sig tl feeders 19 of any make or design. The

super-pressure lubricator vmay be attached to the machine 28in any determinate Way and, as indicated in Figures 1 and 2,l clamps 29 areI provided,- and engage the beveled walls olfrecesses formed in the heads 2 of the cylinder. Drain openings are formed in the cylinder heads 2 and are closed by means of plugs 30. The oil reservoir 12 may be formed in the base ofthe machine orprovided in any determinate way. It is' observed'that the lubricatorimay be marketed as al unit and designed forspecial machines, and fitted thereto in any preferred Way. The pressurel for o erating the lubricator 1s ordinaril derive from the machine to be lubri- `24, and .is controlled by means of the four-4 way valve 27. The plug 28 of the four way lll() valve 27 may be adjusted to direct the presl same timeexhaust the pressure from the op posite chamber 22. Assuming that the fourwayvalveis adjustedjto suppl the pressure tothe left hand chamber22 the right hand cation with 'the exhaust 25. The istons Vtraveling to the right, as indicated y thearrow in Figure 1,'causes a supply of lu- .bricant to be drawn from the reservoir 12- into the right hand chamber "23 in which a suction is created, the valve 11 beingy open l and the valve 10 closed. At'the samel time' .y

the content of the left hand lubricant cham- Y ber 23, is expelled'therefrom, the valve 9Y being closed and the valve open.: When i the pistons right of the ment to the left the lubricant contained. in 'the right hand chamber 23' is expelled therefrom, and

i passes through the eduction" pipe 17 -into the the machine eader or manifold 15, thence into the distributing pipe 18 'to the parts to be lubricated. Durin to. the left, ubricant is drawn from the reservoir 12 into the left hand chamber 23 to be forced therefrom ,in the next movement of the pistons to the right and directed by the eduction pipe 16 into the header 15 and distributing pipe 18.- The pressure for operating the lubricator being derived from to b e lubricated, it follows that the pressure exerted upon the outer face of the istons 4 'corresponds with the pressure of t e machine, and necessarilyfluctuates with such pressure. 'The inner face of the pistons 4 being of a restricted area, by reason `'of the connection 6, necessarily intensifies the pressure exerted for expellingl'the lubricantand supplying the same to e parts to be lubricated, hence the bearings' or par ipxressure, which is constantly maintained at a Xed ratio higher than the pessur eisting ess o uctuations in such internalpressure.

The lubricatioris constructed with a view;

to re uire: approximately several hoursv for the pistons to travel ther full length of -their one-direction and this represents a stroke in period of operation. When setting the lubricator at -thebeginning of a. period of is desirable to have the pistons of their stroke in none direction. 'Y This is effected' by opening the relief cock 21,". and adjusting the four-way valve 27 so that operation it at the limit ressure, is supplied to an endof the cyll, nider. f The lubricant, having a, free .pas-

A super-pressure lubricatonsuchfas herein'V outlined, isv a desideratum, since it admits of'a film of oil beingconstantlyforced inwardly alon a bearing, thereby preventing corrosive uids, or gases, from entering and attacking the bearings'.

to by Pipingof the device is such that it is susceptible of a Wide field of application and utility, alike suitable for use where actuating pressure originates from 'within or without the ma- '85 chine orparts to be lubricated andthat it furthermore may be employed to coni el a j static head when used as an actuating orce, to deliver a ressure greater than itself, as in the'case w ere a hydrostatic head is used 90 for raising water to a higher level, and again where this same static head as an actuating force can be' made .to deliver a pressure greater than itself, against-itself, as in the case of spraying` cold water into a condensing cylinder.y In such adaptation of the invention tlie four-way valvewo'uld be automaticall operated. j i
